Principal Software Engineer Los Angeles, CA

The Role

The software team at K2 strives to blur the lines between the various types of software development and encourages team members to get into parts of the stack they may not otherwise have experience with. This spectrum includes GNC algorithms (Rust, C++), application software on flight computers (Rust, C++), to embedded software on microcontrollers (Rust, C++), to operating systems (Rust, C++,

C), to HDL programming (VHDL, System Verilog), to test systems (Python), and many things in between. By doing this, we create a stronger team with more capable engineers. For now, this does not include front-end, artificial intelligence, or machine learning development.

As a part of the team, you will be responsible for the development and verification of the software used to fly some of the largest spacecraft that have ever been flown. You will write mission‑critical code that controls propulsion systems, attitude control systems, and power systems to ensure safe and reliable operation of the vehicle. In your first 6 months you will develop core pieces of the software architecture including the strategies for fault tolerance, real‑time control, and telemetry downlink.

In your first year you will implement larger software systems and begin verifying your code using both software and hardware in the loop simulators. In your first two years you will operate your code on multiple spacecraft, demonstrating robust performance in demanding missions.

• Create software architecture for real‑time, fault‑tolerant control of a 20kW+ spacecraft
• Develop software applications for control of spacecraft subsystems, including propulsion, guidance/attitude control, thermal, power, and communications systems
• Design and implement state machines for robust operation of the spacecraft
• Create and utilize robust tools to allow for rapid deployment of quality code
• Perform data analysis and anomaly investigation to identify and resolve software bugs
• Support integration and testing of the spacecraft subsystems
• Build and maintain infrastructure to increase reliability when developing and testing software

• Bachelor's degree in computer science, computer engineering, electrical engineering, math, or a STEM discipline or 10+ years of professional experience in software engineering
• Development experience in Rust, C/C++, Python, VHDL, System Verilog

• Experience with spacecraft flight software development
• Fluency with Linux systems programming and driver development
• Experience with continuous integration and continuous delivery systems
• Experience building or working with hard real‑time embedded systems (bare‑metal or RTOS)
• Basic knowledge of electronics, computer architecture, and control systems
• Experience developing or working with state machines
• Experience with software verification and testing methods
• Experience with software and network performance analysis and debugging
• Experience with implementing Extended Kalman Filters for inertial sensors
• Experience with fault‑tolerant software design and implementation
• Experience defining and creating test systems for both hardware‑in‑the‑loop and hardware‑out‑of‑the‑loop

• Base salary range for this role is $200,000 - $240,000 + equity in the company
• Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level
• Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks

If you don’t meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non‑traditional career twists and turns are encouraged!

We value in‑person collaboration, and prefer candidates that are able to work alongside our team in Torrance, California. However our software team does allow for remote work with the expectation that you spend 1 week per month onsite.

If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know.
